'ram FASTENER Filed Aug. 15, 1939 INVENTOR ATTORN EY Patented Dec. 3, 1940 UNITED `STATES TRIM FASTENER Harold, W. Kost, Birmingham, Mich.asslgnor to 'Detroit Harvester Company, Detroit, Mich., a corporation of Michigan Application August 15, 1939, Serial No. 290,255 io claims. (C1. 24-7s) port, for retaining the trim in position/with re' spect to such support.

Another object of the invention is to provide a fastener with integral snap fastener means in l5 the form of fingers formed entirely of the material of the fastener to produce in effect a multipart fastener from a single strip of sheet metal..

A further object of the invention is to provide a snap fastener with an integral resilient finger, g@ or aperture engaging arm, permitting ready installation in an aperture in a paneL,l or the like, and at the same time providing a substantially permanent attaching means for the trim.

Further objects and advantages will become 25 apparent from a study of the following description when taken in connection with the accom-l panying drawing, in which:

Figure l is a perspective View illustrating a form of trimfastener'embodying the present invengg tion; l

Figure 2 is a vertical sectional detail view illustrating the fastener of Figure 1 in use;

Figure 3 is a vieu similar to'Figure 1, illustrating a modified form of the invention; 35 Figure d is a view similar to Figure 2, but -illustrating the fastener of Figure 3;

Figure 5 is a vertical sectional detail view illustrating a still further form of the invention;

Figure 6 is an elevational view'of the fastener 4@ shown in Figure 5; and

' Figure 7 is a view similar to Figure 5, but illustrating a still further form of the present invention.

Referring to the drawing, and particularly to.

the embodiment of the inventionillustratecl in Figures 1 and 2, a trim fastener, indicated generally at it, comprises a head portion l2 and a.

itself and into engagement with the lower surface 255 of the top i5. The other end of the top is like'- wise bent back upon itself to form an arm l 'l from which the stud or body portion I4 depends.

Stud portion It comprises a pair of comparan tively rigid leg portions 20 and 2l interconnected by an intermediate portion 22 remote from the head l2. The leg 20 has its free end portion 23 disposedadjacent the head l2, the other leg 2i being integrally connected to an arm of the head. The leg portions 2t and 2l are slightly angularly disposed and converge toward the intermediate 10 or connecting portion 22, and each leg has a yieldable snap fastener means formed therein. 'I'he snap fastener meansor members comprise a pair of fingers 24 having diverging portions 25 and. converging portions 26 providing shoulders 3g at 21 for engagement with the cooperating apertured part or panel 29, as shown in Figure 2. .The fingers 2d are connected together by the connect- 3 ing portion t2 of the legs 2@ and 2l to form a nose or leading edge on the stud for guiding the im latter into engaging relationfwith the aperture.

' The other ends of the fingers are free and are disposed adjacent the head portion but spaced therefrom to provide for the reception .of the panel and trim material. Thus the fastener comgg lprises a single piece of material in which is fastener has been illustrated in which the fas- (tener indicated generally at 35, comprises a head portion 35 having a trim engaging finger 3l and a trim engaging arm adapted to be bent back upon itself into parallelism with the head 36 to y embrace a portion of the trim therebetween, as particularly shown in Figure fl. The trim erigaging finger and arm has been illustrated as formed out of the same end portion of the head, the finger :il being stamped out of the arm and a producing an aperture f3@ as a result of taking material from'the end portion of the head for forming the nger. The arm 32 is preferably bent upwardly for insertion in an aperture i2 in the trim material, the arm t being subsequently 5 bent back upon itself to embrace one face of the trim. The stud or body portion of the fastener Sfis similar to that described in connection with the fastener illustrated in Figures land 2, and is connected to the head by a connector Wall tta. g@ It comprises a pair of arms @i3 and @d provided with spring fingers l5 and it respectively in the arms and arranged in a like manner to those of Figures l and 2.

The form of the invention illustrated in Figures 5 and 6 comprises a trim fastener 50 having a head portion 5|, one end of which is bent back upon itself to form a substantially parallel arm 52 engageable with the trim material, as in the previously described forms of the invention. Another arm 53, also parallel to the top portion 5I, is formed at the other end thereof, from which arm a stud portion 54 depends. Stud portion 54 is bent back upon itself at a point remote from the head portion to form a loop having an upwardly extending arm 55, the upper extremity of which is reduced in width and provides a lip or tongue 51 receivable in an opening 58 in stud portion 54 adjacent the head. The opening 58 is of a size to permit relative movement of the lip 51 therein, in order that the stud portion 54 may* be inserted through an aperture in a panel or like support. It will be noted that the form of fastener shown in Figures and 6 is fabricated from a single strip of comparatively narrow sheet material providing an integral structure having a trim engaging head portion and a ldepending stud portion arranged to be snapped into fasten ing engagement with the walls of a suitable aperture.

In Figure 7, a slightly modified form of fastener from that shown in Figures 5'and 6, has been illustrated as comprising a unitary fastener structure indicated generally at 60.` The fastener includes a head portion 6| provided with inturned arms 62 and 63 arranged parallel to the top faceof the head. From one arm 63 extends a stud portion 64, bent back upon itself to provide an upwardly extending arm or leg 65 terminating in a slightly outwardly extremity or lip 61. It is to be noted that in this form of the invention the lip 61 lies adjacent the juncture of the arm 63 andthe stud portion 64, and is arranged so that upon insertion in a suitable aperture, relative movement between the lip and the stud 64 is permitted; Thus, during installation it will be noted that the stud portion is compressed, and

being of suitable resilient material,l expands into'v engagement with the aperture to securely retain the fastener in position and thus hold the trim or upholstery material in its desired position.

Heretofore fasteners of this type have been formed with open ends on the holding arms and these are sharp and sometimes cause lacerations to the fingers of those who are engaged in assembling these fasteners( Many times in assembling l fasteners with open ends, one side of the clip impinges upon a side of the hole through which the clip is to be assembled andthe operator, in trying to force the clip through the hole, attens 4one .y leg of the clip, thereby making it necessary to insert a new fastener and start all over. These dimculties are overcome in the above fastener which provides a smooth entering surface comprised of the U-shaped connector wall 22, thereby allowing the clip to ,enter the hole easily and.

precluding anypossibility of nger lacerations or the flattening of one leg of the clip as described above.

. inserted into the aperture.

It will be apparent also that-various modifications other than those herein shown and described, may, be made in the structure without departing from the spirit of the invention.
